Student Exchange Programs

Is there really website which allows the general public to use satellites in order to narrow in on a specific location (such as a neighborhood or specific homes)?

One of my professors stated a foreign exchanged student - which after receiving his degree returned to their home country - and would call her at specific time (mainly shortly after entering her home)…. when the professor stated to the former student on how well their timing was - they stated that they had seen the professor was just arriving home (giving her time to unpack her groceries, etc) and they were viewing it through a website which allows the general public to pin-point areas.

If this is true and is offered to the general public how do you find it?

Also wouldn’t this be against the law; considering people could potentially stalk others?

I’d like to see it - just so I can believe it and would also like to be able to tell the professor of the exact website so she, too, make check it out.

Thanks
